Iridescent beauty defines the plumage. Noisy gregarious habits define the behaviour. In breeding plumage black feathers shimmer with green and purple. A glossy oil-slick sheen catches the light. Winter brings a change. The bird becomes covered in white spots. The pattern gives it a completely different appearance. Starling is a shapeshifter. It looks different depending on season. And the angle of the light. Visual identity is fluid. Adaptation is constant. The bird wears its environment. Introduction to New Zealand happened in the 19th century. From Europe. Part of the same wave of acclimatisation that brought blackbirds thrushes and sparrows. Thriving followed. Abundant food in farmland and gardens supported growth. Abundant nesting sites in tree hollows and buildings helped too. Today the starling is one of the most common birds in the country. Particularly in rural and urban areas. It fits. It stays. It multiplies. The integration is seamless. Social nature is key. Almost always found in flocks. Flock feeds on ground. Walking with purposeful slightly jerky gait. Probing soil with strong bill. Diet includes insects worms fruit and seeds. Regular visitor to bird feeders. Competes with other birds for suet and mealworms. In farmland follows grazing animals. Picks insects from grass. And from animals' hides. Symbiosis of convenience. The cow provides. The bird takes. Efficiency drives the partnership. Murmurations bring fame. At dusk in winter thousands gather in the sky. Swirling and diving in coordinated fluid formations. Spectacular sight. Living breathing cloud of birds. Twists and turns against setting sun. Purpose is not fully understood. Thought to be defence against predators. Way to share information about feeding sites. Or simply a way to keep warm on cold winter nights. The mystery persists. The spectacle continues. Observation yields questions rather than answers. Vocal mimicry adds another layer. Incorporates sounds from environment into complex chattering song. Imitates other birds. Car alarms. Mobile phones. Human speech. Call is a mix of whistles clicks and rattles. Delivered with restless energetic quality. Not a beautiful singer. But an endlessly inventive one. Creativity compensates for lack of melody. The bird listens. It repeats. It adapts. The repertoire expands with experience. Nesting occurs in tree hollows. Competes with native birds for this limited resource. Also nests in buildings. Under eaves. In nest boxes. Female builds messy nest of grass feathers and rubbish. Lays four to six eggs. Both parents share incubation and feeding duties. Chicks fledge after about three weeks. Fed by both parents for several more weeks. Cooperation ensures survival. The cycle repeats. Productivity is high. Successful introduced species. Made itself at home in New Zealand landscape. Iridescent plumage. Murmurations. Vocal inventiveness. Hard to ignore. Whether pest or welcome addition is matter of perspective. For many New Zealanders simply part of countryside. As familiar as sheep in paddocks. And gulls on beach. The bird does not care for the debate. It occupies the space. It makes the noise. It lives. No one told it otherwise.
